I was only lurking here and don't have much time to contribute, nor claim to
be an expert at either Surveying or XML.
Seeing as no-one else has mentioned it, Survex has the ability (at least I
think) to specify the estimated Standard Deviation of each value or for a
set of values, this is then a figure which cannot be misinterpreted and can
be used in the loop closure code. Survex provides a set of include files
for the to map from standard BCRA instrument reading grades to the Standard
Deviation of the recorded values.
This would seem to be much more elegant solution than anything else which
has been suggested so far for this and would also avoid throwing away data
from Survex files if converted.
Eventual input software which generates the XML can help with converting
confidence = word to SD = number
